One common theme is redemption. Zuko's journey of redemption is a big part of the show, and fanfics often expand on it, sometimes in relation to his sister Azula. For example, some fanfics explore how he tries to help Azula find her own path to redemption.
Another option is Reddit. There are subreddits dedicated to Avatar fanfiction. You can ask the community for their favorite Zuko and Azula fanfics, and they'll likely be more than happy to share some great reads. There are often discussions about different interpretations of the characters in fanfics as well.
The relationship would change drastically. Before the pregnancy, they were often at odds. But now, they are bound by this new situation. Zuko would probably be more involved in Azula's life, and Azula might start to trust Zuko more. They would have to communicate better to deal with the upcoming challenges of having a baby, like preparing a nursery, choosing a name, and dealing with the reactions of their family and the court.
